This paper investigates the relationship between immigration and inequality in the UK over the past forty years. This is a period when the share of foreign-born in the UK population increased from 5.3% in 1975 to 13.4% in 2015. We evaluate the impact immigration had on wage inequality in the UK...

We study incumbency advantage in markets with positive consumption externalities. Users of an incumbent platform receive stochastic opportunities to migrate to an entrant. They can accept a migration opportunity or wait for a future opportunity. In some circumstances, users have incentives to...

The process of matching between firms and workers is an important mechanism in determining the distribution of wages. In a labor market characterised by large dispersion of workers' productivity and worker-firm complementarity, high quality firms have strong incentives to screen for the quality...

We use a multilevel approach to characterize the relationship between weather shocks and (internal and international) migration intentions. We combine individual survey data on migration intentions with measures of localized weather shocks for Western African countries over 2008-2016. A...

This chapter undertook the monumental task of providing a complete outlook about return, repeat, circular and onward migration by bringing together the perspectives of the host and the home country. In this endeavor, it reviewed and evaluated all theories about why people move, when they...

Do labor market concerns affect support for immigration? Using a large, representative sample of the US population, we first elicit beliefs about the labor market impact of immigration. To generate exogenous variation in beliefs, we then provide respondents in the treatment group with research...

We analyze the welfare effects of trade and migration, focusing on two-sided horizontal heterogeneity among workers and firms. We prove the existence of a unique symmetric equilibrium in a two stage game of firm entry (including choice of skill-types) and pricing, involving monopsony power on...

We investigate the relationship between the presence of migrant inventors and the dynamics of innovation in the migrants’ receiving countries. We find that countries are 25 to 50 percent more likely to gain advantage in patenting in certain technologies given a twofold increase in the...

This paper estimates the impacts of climate change in sub-Saharan Africa (SSA) on migration and other economic outcomes. I develop a quantitative spatial model that captures the role of trade networks, migration barriers, and agricultural yields on the geography of the economy. I combine the...
